*Standard Clear atmosphere; Extinction Coefficient 0.0448 @ 1,570nm (Modtran 3 V1.5; tropical atmosphere, maritime aerosols, Jan.); sea level visibility = 23.5km.
**Target albedo = 0.3 @ 1,570nm.

Sealing

  • Hermetic

Laser Safety

  • Class 1M ***
***AS/NZS IEC60825. 2011.

Transmitter

Laser type diode pumped Nd:YAG/OPO
Wavelength 1,570 nm
Output nominally 8mJĀ  [to Class 1M limit]
Ranging rate 10Hz typical, up to 20Hz (with duty cycle)

Detector

  • InGaAs with time variant gain

Range Determination

  • Signals from the detector are digitally sampled and examined to determine all potential real target returns. An adaptive range threshold compensates for changing noise levels, maximising system capability under varying conditions.

Power

  • 12 to 32Vdc input

Comms

  • RS-422 19,200 Baud

Mounting

  • V-block type

Reference Laser
